In its third rebuke of the Bush administration's treatment of prisoners, the court ruled 5-4 that the government is violating the rights of prisoners being held indefinitely and without charges at the U.S. naval base in Cuba. The court's liberal justices were in the majority.

Justice Anthony Kennedy, writing for the court, said, "The laws and Constitution are designed to survive, and remain in force, in extraordinary times."

Kennedy said federal judges could ultimately order some detainees to be released, but that such orders would depend on security concerns and other circumstances.

The White House had no immediate comment on the ruling. White House press secretary Dana Perino, traveling with President Bush in Rome, said the administration was reviewing the opinion.
